 ## How?
 
-A frak pattern is constructed from a very stupid trie of characters.
-As characters are added to it, meta data is stored in it's branches.
-The meta data contains information such as which branches are terminal
-and a record of characters which have "visited" the branch.

 During the rendering process frak will prefer branch characters that
 have "visited" the most. In the example above, you will notice the

+While the patterns currently generated by frak are correct, there is

+By using a DAWG it might be possible to produce more efficient

 ## And now for something completely different
 
 Let's build a regular expression for matching any word in
